EU1000 Versus EU2000

Bob,
I have to check to see if there is the added load of a water pump for the Marine 1Ton a/c unit. I realize inverters are not too happy with excess load currents for the PWM most use and the load can knockout the driver/oscillator to the point it could fry the input filters or series caps to the doubler circuit on the preregulator. Either way, if it doesn't protect itself, I buy a new inverter.

So, if I am at that close of a margin, I see 2- EU2000s wired in parallel or 1- EU3000.

As to the frame support for this, it appears that space would dictate the EU3000. The hardware would therefore be 1" SS stock with a shelf located between the twins. This would have to allow removal so the OBs can be raised, if needed. Unlike the 255, the OBs are very close together. Homework is required to see how close all this really is.; especially if we would add the external fuel tank. [I don't know what the the vacuum pull is for the EU3000. I do have 2 RACOR filters under the starboard aft deck seat.]

Art-

I don't know offhand how the weight and dimensions compare, but Yamaha makes a single 2600 watt inverter type generator similar to the Hondas that might fit somewhat between the motors and provide the necessary wattage and surge capacity w/o having two units, although handling two smaller units might be easier than one large one.

Still might be worth looking into as an alternative.

On edit: looks like the 2600 has be reduced to a 2400!

The pumps for the marine AC units draw about an amp--so that has to be included--but there is not the same start up load with the small pump motor.

Joe, I had posted the outputs on the Yamaha EF 2400 is inverter type generator (there may also be a 2600 which I missed)--and it is 2400 max output and 2000 watts continous 16.7 amps continous but weight is 70 lbs, vs the 1600 watts and 13.3 amps for the EU 2000 i. There are folks definately running the 13,500 RV roof airs on the Yamaha.

I was looking at the splash well of my C Dory 25 today and I agree that it would be more difficult to build a rack which would keep the generator clear of the motors with twins. It occured to me that perhaps a rack over the engines would be better on that application---gets complicated?

There is also a Yamaha EF 2800i, which puts out 2500 watts--is lighter (64 lbs) but noiser (60 to 67 dB). It looks more like a "contractor" type of generator.

The EU 2000i will not pull gas up out of tanks which are more than a foot below the top of the built in fuel tank. I am not sure of the other's abliity, but I suspect that the RV literature has this. There have been problems with putting in a pressure fuel pump (overflow of raw gas has been reported). We try and keep our 6 gallon auxillary tank about at the same level as the EU 2000.

Hey Bob and all: I had been thinking of getting a "polling platform" built for C-Byrd to mount over the motor....like the skinny water flats boats have. My thought/concearn was adding another 70 lbs of gen, plus the weight of the platform itself which should not be all that heavy??? This may work on the CD 25s too?? No? Maybe Yes?? I know C-Pearl is also poking about looking for a solution too. Who knows... might get an order for about a dozen of them.

Options of aluminum vs SS for leighter weights?
